HEADLIGHT DIMMER v Filed Oct. 10. 1928 Patented June 24, 1930l i titane CLIFFORD W. BEMAN, or NORTH RMIoRIA, VIRGINIA HEADLIGHT DIMMER Application filed October 10, 1928. Serial No. 311,676.

This invention relates to headlights of the type used upon automobiles and more particularly relates to a dimmer disposed in the headlight about an electric bulb and adapted to shield a portion of the reflector and thereby prevent a glaring light which causes a person approaching the automobile to be blinded.

One object of the invention is to provide a dimmer which may be disposed in the headlight about a bulb and lirmly secured so that ...it will be retained in proper operative relation to the bulb and reflector o'f the headlight.

Another object of the invention is to permit a portion of the light from the bulb to reach the reflector of the headlight but at the same time prevent a glaring light.

The invention is illustrated in the accompanying drawing, wherein j Figure 1 is a view in front elevation showing the shield secured in a headlight in operative relation to a bulb,

Fig. 2 is a vertical sectional view taken on the line 2-2 of Fig. 1 with the bulb and its base shown in elevation, t

Fig-3 is a perspective view of the shield, and

Fig. 4 is a perspective View of a modified aoiform of shield.

The reflector, which is indicated in general by the numeral 1, is of a conventional construction and carries a socket 2 into which is received the base 3 of an electric bulb 4.

The reflector may constitute the body of a headlight or it may be an element thereof and secured in the casing of a headlight in any desired manner.

The shield 5, which is shown lnFigs. 1, 2

40 and 3, is formed from a strip of material which is preferably semi-transparent and may be tinted any color desired. This `strip is bent to extend partially about the bulb, as shown in Fig'. 1, and is provided with openings 6 throughl which a portion of the Vlight ying an automobile will be from the bulb may pass. It will be understood, however, that, if desired, the openings may be omitted. lIhe ends of the strip are rolled to 'form sleeves 7 at opposite sides of the shield and throughV these sleeves are passed bolts 8, the heads of which engage' the forward ends of the sleeves. The bolts are .of suchlength that their threaded ends project rearwardly from the sleeves so that they may be passed through lopenings formed in the reiector and securing nuts 10 applied." Iherefore, the shield willbe iirmly secured 1n its proper position about the bulb and cannot work loose. Since the shield extends about the bulb in'` covering relation to the 60 lower portion of the reector, glaring lights 'i which are liable to blind a person approacheliminated but a road will be very well illuminated. A The form of shield shown inF ig. 4 yconi- 65 sists of strips 11 which extend longitudi-"1` nally of the shield and have their front andV rear'ends rolled about rings 12 and 13 which support the strips in spaced relation to each other. A yoke 14 is carried by the rear ring 70 and consists of a strand of resilient wire coiled intermediate its length to form an eye 15V having arms 16 extending therefrom and anchoredto the ring. When this form of shield isin use, the bulb is removed from its socket and disposed within the shield with its shank Vprojecting rearwardly through the eye of the yoke. The eye fits tightly about the shank and in order to again engage the Y shank within the socket it is necessary to spring the yoke rearwardly as the rear ring bears against the reflector. Therefore, yfric- Vtional binding will take place and the shield will be iirmly held-in a set position but may be moved about the bulb to adjusted positions S5 if so desired. Additional strips 11 may be" added so that the shield will `extend entirely about the bulb.

Having thus described the invention, I

claim:

A headlight dimmer comprising a shield to be disposed in a headlight and extend partially about a bulb in shielding relation to a reflector, the said shield being 'formed of a 'sheet of material having openings formed therein and having its side portions rolled to form sleeves extending longitudinally of the shield, and bolts passed through said sleeves and engaged through the reflector to secure the shield Within a headlight with the shield extending partially about the bulb and projecting forwardly from the surface of the reector.

In testimony whereof I affix luy-signature.
